METALLIC BINDER FOR BOXES.

SPECIFICATION forming part of Letters Patent No. 405,359, dated June 18,1889.

Application filed July 12, 1888. Serial No. 279,793. (Model) To aZZ whomit may concern.-

Be it known that I, FRANK G. JOHNSON, a citizen of the United States,residing in the city, county, and State of New York, have invented a newand useful Metallic Box-Binder for Securing the Corners ofPacking-Boxes, of which the following is a specification.

The object of my invention is to provide a metallic binder for securingthe corners of packing and other boxes, which can be cheaply made andconveniently applied by unskilled labor, and to boxes of various sizes.

The construction of my binder is fully set forth in the followingspecification, reference being had to the accompanying drawings, inwhich- Figure lrepresents one of the said binders as it is applied tothe corner of a box. Fig. 2 represents the square piece of sheet metalwith a small part of the central portion out out, which, when folded,forms the binder, as shown in Fig. 1. Fig. 3 shows the binder as seenwhen looking toward its apex. Fig. 4 shows it as applied to a box andseen when looking toward the apex.

Similar letters refer to similar throughout the several views.

A is a square piece of sheet metal having the central portion B cut out,as seen in Fig. 2. It is not necessary, however, to cut out any part ofthe center, only as it might be desirable, for reasons hereinafterexplained. By bending this square sheet A at right angles on the dottedlines a a a a, Fig. 2, and bending one of its sides inward closely uponitself on the line bbybringing the adjacent corners toward each other,which doubles this side upon itself, then by bending the folded sidedown upon one of the adjacent sides of the square, as shown in Fig. 3,the triangular right-angled corner-binder is formed, as seen in Fig. 1,which is mathematically perfect in form. d d, Fig. 1, represent theheads of parts nails which fasten the binder to the box 0.

The only object of cutting a small piece out of the center of the sheetbefore it is formed, if thought desirable, is to allow the extremecorner of the box 13 to protrude through the binder, as seen in Fig. 1,to prevent the binder from being knocked out of place or bent, as thebox, by handling, may chance to fall upon its corners; hence it will beseen that these metallic binders are not so much intended to protect theextreme corners of the boX as to bind and strap together the threepieces of board that form the corners to prevent them from coming apart.

I am aware that cast-iron corner pieces have been employed as shields oncorners of trunks to protect the same from damage; and I am also awarethat corner-pieces for paper boxes have been made of sheet metal, asshown in patent granted to David Steinburg, No. 21 6,237 also that theyhave been made of cloth and paper for the same use, as shown in patentgranted to George M. Hendrickson, No. 96,108. I am also aware thatstrips of sheet metal have beenemployed to bind the corners ofpacking-boxes, as shown in patent granted to Henry C. Stone, No.106,876. Therefore I do not claim, broadly, the employment of metalliccorners for binders of boxes irrespective of the manner of constructingthe same; but

What I do claim as new and useful, and desire to secure by LettersPatent, is

The jointless sheet-metal binder having three sides at right angles toand inclined toward each other, one side being composed of a mainportion and a folded portion, as set forth.

FRANK G. JOHNSON.
